The Leukemia Cooperative Groups of the EORTC and the GIMEMA conducted a prospective randomized phase III trial, in order to assess the value of autologous BMT (ABMT) vs a second intensive consolidation course (IC2), following a common intensive consolidation course (IC1) for patients with AML. Patients with an HLA-identical sibling donor were not randomized, but were included in an allogeneic BMT (alloBMT) program. This is an analysis of prognostic factors which influence the outcome of treatment after alloBMT in first complete remission (CR). The study included 730 patients < 46 years of age in CR, 270 having a histocompatible sibling donor. In 169 of these patients alloBMT was performed in first CR. Early remitters (122 patients achieving CR with one course of treatment) had a DFS at 3 years of 67%, significantly longer than that of 44% for late remitters (47 patients achieving CR after more than one course of treatment) (P = 0.006). The relapse risk for early vs late remitters was 16 and 40% at 3 years (P = 0.001) and the treatment-related mortality (TRM) at 2 years was 21 vs 27%. Age appeared to be a prognostic factor for TRM, WBC for DFS, whereas the FAB classification was not of prognostic importance. Patients with poor risk cytogenetic abnormalities showed a trend towards a higher relapse risk. Patients transplanted shortly after achieving CR appeared to have a worse prognosis than those transplanted further into remission. Overall, the number of courses of induction therapy needed to achieve CR was the most important prognostic factor for outcome after allogeneic BMT.

To determine whether patients with a HLA-identical sibling donor have a better outcome than patients without a donor, an analysis on the basis of intention-to-treat principles was performed within the framework of the EORTC-GIMEMA randomized phase III AML 8A trial. Patients in complete remission (CR) received one intensive consolidation course. Patients with a histocompatible sibling donor were then allocated allogeneic bone marrow transplantation (alloBMT), the patients without a donor were randomized between autologous BMT (ABMT) and a second intensive consolidation (IC2). 831 patients <46 years old and alive >8 weeks from diagnosis were included. HLA typing was performed in 672 patients. AlloBMT was performed during CR1 in 180 (61%) out of 295 patients with a donor. Another 38 patients were allografted: five in resistant disease, 14 during relapse and 19 in CR2. ABMT was performed in 130 (34%) out of 377 patients without a donor in CR1, in six (2%) patients during relapse and in 38 (10%) patients during CR2. The disease-free survival (DFS) from CR for patients with a donor was significantly longer than for patients without a donor (46% v 33% at 6 years; P=0.01, RR 0.78, 95% confidence interval 0.63-0.96). The overall survival from diagnosis for patients with a donor was longer, but not statistically significant, than for patients without a donor (48% v 40% at 6 years; logrank P=0.24). When patients were stratified according to prognostic risk groups, the same trend in favour of patients with a donor was seen for survival duration and the DFS remained significantly longer for this group of patients.
